Roedean, New Construction Series

[Nicholas FarrParticipant @nicholasfarr14254]

Hi David, have just read the first installment of LBSC’s Roedean, a welcome return of the “Words and Music” in my view. I must admit to not reading any of his writings for some while now, but have always enjoyed reading his constructional notes, as he always seem to give alternative ways of producing many of the components, especially the things like the buffer/drag beams, bogie bolsters and pump stays ect.

 

I think this will be an interesting series to read, thanks.

 

Regards Nick.

He had a wonderful way with language; he was clearly well read as he managed to pile in references from railway esperanto, the old testament and the classics, among others, but although he always spoke as a ‘mentor’ he was never (rarely) patronising.

Hi There

We are reprinting the frames drawing as it is not clear enough in the first article.

regards David

Hi All

 

Wouldn’t a deal on a set of drawings have been a good idea to accompany the series?

Hi There

I am workinh on this.

We never had a copy of the original drawings as they were from Mechanics.

I do have a copy scanned in but need to get them a bit tidier.

If there is enough interest, I can have them made available.

regards David

David,

I hope you are better.

I was reading part 5 of Roedean by LBSC (ME Vol 207 No 4412) and looking at the Cylinder Drawings I noticed ‘Ole Curley’ had decided to fit it with ‘piston valves’. Within the past year there was a ‘Letter to the Editor’ in ME on this problem. The gentleman who wrote it concerned with Hydraulics. He pointed out that in hydraulic control gear ,where piston valves were used, the cylinders were pierced with numerous small holes instead of the large steam passage. The valve spools were sealed with ‘O’ rings. I remember that you as Editor commented favourably on this idea.

Curley’s valves cylinders are 0.5” ( 12.7mm) inside diameter. If the holes were say 1/16” (1.6mm) diameter were drilled so that they would have 1/8” (3.2mm) between the centres when measured on the ID of the valve cylinder you could have 12 such holes in s single band of holes. The area of 1 row of such holes would be some 24 sq mm

May I suggest that when ‘Ole Curley’ describes the valve gear you reprint the gentleman’s letter
